FIELD OF THE DISCLOSURE

The present invention relates to recognizing objects in video images, and more particularly, to systems and methods for recognizing objects in video images captured by 360° field-of-view fisheye cameras.

BACKGROUND

While image processing Artificial Intelligence algorithms are quite popular on identifying objects of interest (object detection) within a given image frame or series of frames (video), they are based on the principle that an image frame is rectangular and the objects will always appear with their default orientation. More specifically a deep learning framework is trained to identify the objects of interest by supplying to it a big number of frames encapsulating and designating these objects. Since the cameras used to capture the objects of interests are 2-Dimensional, the objects will always appear with their “natural” orientation. At least some known deep learning framework algorithms are trained to recognize, classify and track objects of interest when these objects appear with their natural orientation. These algorithms fail to recognize the object of interest when the object appears rotated at an angle different than its nominal one.

The present invention is aimed at one or more of the problems identified above.

DETAILED DESCRIPTION

With reference to the drawings and in operation, the embodiments of the present invention provide a system for recognizing objects appearing in video images captured with 360° field-of-view (FOV) camera and determining the geographic coordinates of recognized objects.

Referring to FIGS. 1-4 , in the illustrated embodiment, the present invention includes a system 10 that is programmed to detect and recognize objects in live-stream video images, determine the geographic locations of the recognized objects in near real-time, and generate a graphic user interface on a device display that includes a presentation of the video images including visual indicators of the recognized objects and corresponding geographical coordinates. The system 10 includes an object recognition system 12 and a training system 14. The object recognition system 12 is coupled to one or more imaging devices 16 for receiving live-stream video images from the imaging devices 16 and detecting and recognizing objects 18 appearing in the live-stream video images 20. The imaging devices 16 may include, for example, a Quantum 360™ Rover Camera™ sold by Defender™ LLC. The training system 14 is programmed to generate an image recognition training model 22 that is used by the object recognition system 12 to detect and recognize the objects 18 appearing in the live-stream video images.

The object recognition system 12 includes an object recognition component 24, an object geolocation component 26, and a content component 28. The object recognition component 24 is programmed to receive live-stream video images from the imaging devices and identify recognized objects appearing in the live-stream video images. For example, the object recognition component 24 may configured to perform recognition processing of the objects 18 in the video 20 to, for example, identify a specific object (e.g., person) or multiple objects (e.g., people, vehicles, drones, items, etc.) where the recognition processing is performed using the training model 22.

The object geolocation component 26 is programmed to determine a geographic location of the objects 18 recognized by the object recognition component 24 including the object's geographic coordinates 30. The content component 28 is programmed to generate and display a graphic user interface 32 including a presentation of the video 20, one or more recognized objects 18, and corresponding geographic coordinates 30 in a device display 34. For example, the content component 28 may be programmed to distribute the presentation to one or more client personal devices 36. The client personal devices 36 may include, for example, tablet computers, laptop computers, desktop computers, smart phones, and the like, that may be used by users watching the video images 20. The presentation may include a video window 38 in which the live-stream video image 20 is presented. The presentation may also include a visual indicator 40 of the recognized object 18 and display the corresponding geographic coordinates 30 adjacent to the visual indicator 40. The video window 38 can include various controls and indicators 42 such as forward, pause, fast forward, reverse, fast reverse, speaker volume control, and so on, commonly associated with user controls in viewing a video.

The training system 14 includes a training component 42 that is programmed to train the training model 22 using training data 44. The training component 42 can be configured to derive and output training data 44 from video images, and use the training data 44 ultimately for identification of objects 18 in the video 20 via the training model 22. The training component 42 may also be configured to train the model 22 using a set of tagged (labeled) images of the objects 18 to learn features of the objects 18. For example, images of objects that are desired to be recognized can be obtained and tagged for training the model 22. The training component 42 may include an artificial intelligence (AI) system 46 that processes full-frame 360-degree video and still images.

The AI system 46 may include an artificial neural network (ANN) including a machine learning network comprising a number of highly interconnected processing elements (artificial neurons) that process information by their dynamic state response to inputs including inputs dependent upon the dynamic state response of interconnected artificial neurons. It can be, for example, a shallow neural network, deep neural network (DNN), a recurrent neural network (RNN), Convolutional neural network (CNN), a Generative adversarial network (GAN), a Capsule Neural Network (CapsNet), etc. The ANN may include a number of highly interconnected processing elements (artificial neurons) that process information by their dynamic state response to external inputs. The ANN may be arranged as a directed graph whose nodes are artificial neurons and whose vertices are connections between artificial neurons. Each neuron can be configured to determine whether or not a weighted sum of its inputs causes an activation function to produce an output. In a layered ANN, an input layer is the first layer and receives at least some of its inputs from outside the ANN and an output layer is the final layer and provides at least some of its outputs outside the ANN. The layers between the first and final layer are hidden layers. For artificial neurons in the hidden layer(s) and the final layer, the inputs are outputs from the artificial neurons in the preceding layer.

An artificial neural network can be defined in hardware using a hardware component for each neuron and physically interconnected the hardware components to form the artificial neural network. For example, each artificial neuron may be simulated using programmed instructions that are executed by a controller. Each artificial neuron may also be a different controller or other circuitry configured to perform the neuron's function. An artificial neural network can be defined in software for example using Python, Matlab or Octave.

Each component may include one or more server computers that each include a processing device that includes a processor that is coupled to a memory device. The processing device executes various programs, and thereby controls components of the server according to user instructions received from the other servers. The processing device may include memory, e.g., read only memory (ROM) and random-access memory (RAM), storing processor-executable instructions and one or more processors that execute the processor-executable instructions. The components of the system 10 may be communicate via a communications network such, as, for example, the Internet, a cellular telecommunications network, a wireless network and/or any suitable telecommunication network.

In the illustrated embodiment, the system 10 includes a networked computer system for recognizing objects in video images. The networked computer system includes a user display device 34, the camera 16, and the object recognition system 12. The camera 16 includes an imaging device having a 360° field-of-view and a global positioning system (GPS) device configured to transmit geographic location data including information indicating the geographic location of the camera 16. The object recognition system 12 includes a processor programmed to execute an algorithm including the steps of receiving live-stream video images from the camera, detecting an object of interest within the live-stream video images, determining pixel coordinates associated with a center of the detected object of interest, receiving the geographic location data from the camera, determining a geographic location of the object of interest based on the determined pixel coordinates and the geographic location of the camera, and displaying the live-stream video images on the user display device including a visual indicator of the object of interest and the determined geographic location of the object of interest. In some embodiments, the system 10 also includes a training system 14 programmed to generate an image recognition training model 22 for use by the object recognition system 12. The training system includes an artificial intelligence (AI) system programmed to processes full-frame 360-degree video images to train the image recognition training model. The processor of the object recognition system 12 is programmed to execute the algorithm including the steps of accessing the image recognition training model for use in detecting the object of interest within the live-stream video images.

With reference to FIGS. 2-21 , in the illustrated embodiment, the system 10 may be programmed to execute the algorithms 200 and 300 for detecting objects in video images received from an imaging device having a 360-degree FOV. The methods include a plurality of steps that may be performed independently of, or in combination with, other method steps. Portions of the methods may be performed by any one of, or any combination of, the components of the system 10.

In method step 202, the training system 14 is programmed to generate the training model 22 and train the object recognition component 24 to recognize desired objects appearing in video images received from the imaging device 16 including a 360-degree FOV fisheye camera.

Deep learning frameworks are trained to identify a person (e.g., object of interest) by a conventional 2-Dimensional camera (for example a smartphone camera) and classify the object as a “person”. The classification includes a “certainty index” signifying the amount of confidence that the detected object is a “person”. Readily available databases have been created that can be used to train the deep learning frameworks by supplying them with a big number of “object of interest” images. Different libraries exist for training these networks to identify, classify and track various types of objects. Problems arise when the cameras used to identify the objects are rotated in any axis, so the object of interest does not appear with its natural orientation. For example, a deep learning framework that was trained to identify a person in a natural orientation, does not recognize it when the camera is rotated because the object appears tilted inside the camera frame. Deep learning framework algorithms are trained to recognize, classify and track objects of interest when these objects appear with their natural orientation (shown in FIG. 5 ). These algorithms fail to recognize the object of interest when the object appears rotated at an angle different than its nominal one (shown in FIG. 6 ).

In the case of the fisheye cameras the objects orientation within the frame is directly related with the spatial relationship of the object with regards to fisheye lens. As shown in FIG. 7 , a person is standing in 4 different cardinal directions around a fisheye camera include: Object position 1: Person stands on the “0 degrees axis” of the fisheye camera; Object position 2: Person stands on the “90 degrees axis” of the fisheye camera; Object position 3: Person stands on the “180 degrees axis” of the fisheye camera; and Object position 4: Person stands on the “270 degrees axis” of the fisheye camera. For each one of these objects positions the respective fisheye camera image frame is shown in FIGS. 8-11 . The object rotation as a spatial relationship with regards to the camera location is shown in the image shown in FIG. 12 taken from a 180 degrees fisheye camera. As shown in the images, a fisheye camera can only utilize known deep learning algorithms in precisely the frontal region of the camera because this is the only region where object will appear undistorted (without rotation). Objects that appear in different regions of the camera Field of View will not be processed by these deep learning framework because these objects appear rotated.

In the illustrated embodiment, the system 10 includes an AI system 46 that processes full-frame 360-degree video and still images in one pass. In doing so, the system 10 is able to detect multiple objects, either in motion, or stationary and regardless of its size, location, or orientation. Using this process, the system 10 will detect an object even it is not in the user's current field of view.

The system 10 takes the inputs from specialized cameras that outputs the full 360-degree video/image from a single-lens. The inputs are very unique, in that it does not require any stitching as it comes from a single lens. Traditional methods of applying object detection is done on inputs with a standard aspect ratio of 1:1, 4:3, 16:9, or 2.4:1 in a traditional “square”.

Currently, there exists multiple AI/ML models that will detect objects using the standard aspect ratios. However, those models are limited as they do not account for the objects not only changing size, but also changing orientation multiple times as it moves across the entire frame of the video.

The method of training used by the system 10, as described herein, accounts for objects no matter their orientation, location, or size. Additionally, the methods used by the system 10 ensures that the object is tracked as it moves across the entire 360-degree frame. In practical terms, an object approaching can look right side up when approaching the viewer and will appear to be rotated when moving past the viewer.

Training: The training of the system 10 first starts with the utilization of a deep learning neural network for an initial extraction of the features. The features are also matched up with the labels and the output is saved for further refinement. The neural network used for this initial feature extraction is trained on the publicly available object training sets. Once the initial features are extracted, the system 10 fine tunes the features and evaluate the features to ensure they match the labels generated. In training the models, the system leverages both CPU and GPUs.

In the next step, the updated feature set is run through a few more algorithms to generate multiple versions of the object in a randomly rotated and sized manner. The algorithms also randomly generate multiple versions of the object at varying distances.

The steps above allow the system to have the ability to detect an object, no matter where it is located in the input or what its rotation is.

The data is then split up into a two sets of data, one for training and one for testing—thus ensuring the system has source of truth by which to measure precision, recall, mean average precision and also allowing the system to generate the feature maps.

The actual model is based on the utilization of a combination of the standard Convolution Neural Network and a single shot detector architecture (SSD) to make a single pass and thus increase the accuracy of the system. The system is trained over 53 layers. To allow for detection of multiple objects and reduce training bias, the system also includes the public image dataset in the training along with the training inputs developed.

After the training of the model is complete, the system evaluates outputs and then updates the features and hyperparameter tuning to increase the precision and recall as well as speed. Next, instead of retaining the entire system, the system 10 utilizes transfer learning to start the training from layer 45 and add in another 20 layers.

Once the training is complete, the model is run against the test dataset and continue hyperparameter tuning; however, randomized test sets are continually introduced to ensure the system does not overfit the model.

Implementation: After the model has been trained, the system 10 saves the serialized model for production. The model is placed into a custom system that takes inputs, runs them against the model, and generates an output of pixel coordinates.

The system 10 uses websockets to provide for real-time output communication with the front-end system, thus allowing for a reduction in overhead normally associated with RESTful APIs.

The system 10 takes an input either in the form of an image or an RTSP video from a camera. The system 10 will process any video inputs into single frame images. The images, once transformed, will then be passed to the model which will configured to output text that will state the pixel coordinates for the nearest center of mass for every object detected in the frame.

As each frame or image is processed, it will be output in JSON format and broadcast out to the websocket so that every authenticated client connected to the websocket can receive the inputs for processing.

Once the front-end system receives the pixel coordinates, it can then further allow the user to determine which types of objects they wish to see as well as draw bounding boxes (or circles) around the detected objects.

The output will also be saved into a database along with the input video to allow for further updates to the training of the model.

As shown in FIG. 13 , as an outcome, the new method will detect the objects of interest no matter their rotation inside the frame. For example, the image shown in FIG. 14 shows the proposed method detecting vehicles in all orientations within the fisheye Field of View and deriving their pixel coordinates.

In method step 204, the object recognition system 12 is programmed to receive video images from the imaging devices 16 and recognize desired objects 18 in the video images using the training model 22. For example, the object recognition system 12 may receive data from the imaging devices 16 including live-stream video images captured from a 360-degree FOV fisheye camera and telemetry data including, but not limited to, a geographic location, elevation, and orientation of the imaging device 18.

In method step 206, the object recognition system 12 determines a geographic location of the recognized objects 18. For example, the object recognition system 12 may be programmed to transpose the fisheye pixel coordinates to calculate the detected object's geographic coordinates.

The fundamental principle of fisheye lenses is that every pixel of a hemispherical fisheye lens can be projected on a fisheye disk as shown in FIG. 15 . The fisheye disk is how the imaging sensor represents the images (frames) created by the fisheye lens as shown in FIG. 16 .

Referring to FIGS. 17-20 , every pixel (or small object occupying a small number of pixels) appearing inside the fisheye circle can be represented by a pair of φ (yaw) and θ (tilt) angles that correspond to a given pair of pixel coordinates inside the fisheye circle (as long the resolution of the fisheye circle is given, for example 1440×1440 pixels). For example, as shown in FIGS. 19 and 20 , the pair of the horizontal fisheye pixel x=720 and vertical pixel y=1260 correspond to the pair of pan angle, φ=90 degrees from the top (nadir) of the fisheye image and the tilt angle, θ=45 degrees above the horizon.

This analogy allows the system 10 to correspond every pair of pixels the center of an object appears to a pan/tilt angle using the simple trigonometric functions based on the right-angle theorem using the algorithm 300 shown in FIG. 21 .

When the fisheye lens is mounted on an elevated location and pointing towards the ground (lens normal to the ground), as long as its location and elevation is known and its orientation (attitude) with regards to the horizon and the True North is also known then subsequently the bearing and tilt angle can be used to derive the latitude and longitude of the corresponding object from the formulas below:

Formula 1: Given a start point, initial bearing, and distance, this will calculate the destination point and final bearing travelling along a (shortest distance) great circle arc. k ₂ =a sin(sin k ₁·cos δ+cos k ₁·sin δ·cos φ)  Equation (1): λ₂=λ₁ +a tan 2(sin φ·sin δ·cos k ₁, cos δ−sin k ₁·sin k ₂)  Equation (2):

where k is latitude, λ is longitude, φ is the bearing (clockwise from north), δ is the angular

distance d/R; d being the distance travelled, R the earth's radius.

Formula 2: Distance between camera and target object=camera elevation/sin θ  Equation (3):

where θ is a tilt angle.

This process allows the system 10 to input to algorithm a pair of fisheye pixels and derive their corresponding geographic coordinates utilizing 2D mathematics only and without having to rely on image processing techniques for dewarping the fisheye image. This approach utilizes minimal processing power and can run in a low powered processing unit for example inside the processor camera itself.

In some embodiments, the processor of the object recognition system 12 is programmed to execute an algorithm including the steps of receiving live-stream video images from the camera 16 and detecting an object of interest 18 within the live-stream video images, determining pixel coordinates associated with a center of the detected object of interest 18. The processor of the object recognition system 12 also receives the geographic location data from the camera, determines a geographic location of the object of interest 18 based on the determined pixel coordinates and the geographic location of the camera 16, and displays the live-stream video images on the user display device 34 including a visual indicator 40 of the object of interest 18 and the determined geographic location of the object of interest 18.

For example, the processor of the object recognition system 12 may be programmed to determine the pixel coordinates including an x-coordinate and a y-coordinate and determine the yaw angle φ based on the x-coordinate and determine the tilt angle θ based on the y-coordinate. The processor then executes Equations (1), (2), and (3), to determine the geographic location of the object of interest based on the yaw angle φ and the tilt angle θ.

In some embodiments, the processor of the object recognition system 12 receives the geographic location data from the camera 16 including an elevation of the camera 16 and determines the geographic location of the object of interest 18 based on the elevation of the camera 16 using Equation (3). The processor determines the angular distance δ of the object of interest 18 based on the elevation of the camera 16 and the tilt angle θ. For example, the processor determines the distance, d, between the camera 16 and the object of interest 18 using Equation (3), then determines the angular distance δ equal to d/R. The processor then determines the geographic location of the object of interest 18 based on the determined angular distance δ.

The processor of the object recognition system 12 is also programmed to receive the geographic location data including a camera bearing and determine a bearing φ of the object of interest 18 based on the camera bearing and the yaw angle φ. The processor then determines the geographic location of the object of interest 18 based on the determined bearing φ of the object of interest 18 using Equations (1) and (2). For example, the processor may receive the geographic location data including a latitude k₁ and a longitude λ₁ of the camera 16 and determine the geographic location of the object of interest 18 including an object latitude k₂ using Equation (1) and an object longitude λ₂ using Equation (2) based on the latitude and the longitude of the camera using Equations (1) and (2). The processor may then display the visual indicator 40 including the object latitude k₂ and the object longitude λ₂.

In method step 208, the object recognition system 12 generates and displays the presentation on the device display 34 of one or more client devices 36 displaying the live video images 20 indicating the recognized objects 18 and the corresponding geographic coordinates 30.

Importing the derived pixel coordinates of the detected object within the fisheye image into the algorithms described herein allow the system 10 to accurately calculate the real geographic coordinates of the detected object using simple mathematics that do not require image processing techniques. The only image processing part required is to run the deep learning framework that is responsible for the object detection, classification and tracking. But this process is independent of the geolocation calculation that works not only with detected objects pixel coordinates derived by deep learning frameworks but for every object that appears within the fisheye lens field of view. The deep learning framework can either run on a host computing device adjustment to the camera (on the edge) for example an NVIDIA GPU or being on a remote server (cloud based). Both architectures will detect the objects and will return the pixel coordinates to the algorithm described above.
